摘要：

The paper represents the study of the kinetics of diffusion-induced recrystallization (DIR) and its effect on the disordering and creep resistance of an alloy based on Ni3Al doped nickel aluminide. Recrystallization was observed in the Ni3Al-based alloy hardened by the particles of chromium carbides at a temperature of 1573 K due to dissolution of carbides and diffusion of chromium in the volume of grains. Recrystallization leads to a sharp decrease in the creep resistance of the alloy due to the formation of an unordered gamma phase. The alloy can be used as a heat-resistant material at a temperature of not more than 1500 K.
